Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging, in particular to a hopper guiding device for continuous packaging. Background Art

[0002] When packaging powder dye products, an important production indicator is production volume, that is, the number of packages per unit time. Based on the existing configuration of packaging machines, if you want to increase production, you can only improve the efficiency of workers' packaging operations.

[0003] The current operation mode is to manually feed the materials under the packaging machine. Since the packaging machine has only one feeding pipe, there is a limit to the improvement of packaging efficiency. Even if two workers are assigned, they can only stop feeding and close the valve after one person has finished feeding the materials, and then start bagging. The time for opening and closing the valve and the time for alternating bagging will delay production and make the operation inconsistent. Utility Model Content

[0028] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0029] Example:

[0030] The present device includes a butt joint pipe 2, the top end of which is used to be connected and fixed to the discharge pipe of the packaging machine. In terms of the connection structure, it is recommended to set a mounting flange 1 at the top end of the butt joint pipe 2, and to achieve docking with the bottom end of the discharge pipe of the packaging machine through the flange and bolts. This is not limited to this example, and direct welding fixation or other fixed mounting structures can also be used.

[0031] The butt joint pipe 2 is a vertically extending cylindrical shape, and guide pipes 3 are symmetrically arranged on both sides of the butt joint pipe 2. The top of the guide pipe 3 is connected and fixed to the side wall of the butt joint pipe 2. The guide pipe 3 extends downward at an angle of 45 degrees to the butt joint pipe 2. The bottom of the guide pipe 3 is provided with a beveled discharge port 4 for easy insertion into a packaging bag. The tops of the two guide pipes 3 and the side walls of the butt joint pipe 2 are provided with a butt joint 5 that connects the two.

[0032] By extending the guide tube 3 in the reverse direction, two packaging stations with a certain distance between them are separated below a feeding tube, so that two workers can operate at the same time, and the operations of putting on and removing bags by two people do not interfere with each other, and they can work independently.

[0033] An inner lining tube 6 rotatably connected thereto is provided inside the butt joint tube 2, the top side opening of the inner lining tube 6 is 10 cm lower than the top end opening of the butt joint tube 2, the outer diameter of the inner lining tube 6 is adapted to the inner diameter of the butt joint tube 2, an annular boss 7 is provided on the inner wall of the butt joint tube 2, the cross section of the annular boss 7 is wedge-shaped, and an annular guide slope is provided on the top surface, the inner circle diameter of the guide slope is smaller than the inner diameter of the inner lining tube 6, the annular boss 7 is provided above the top end opening of the inner lining tube 6, thereby the powder can be well introduced into the inner lining tube 6 to avoid accumulation at the top side opening of the inner lining tube 6.

[0034] The side wall of the inner liner tube 6 is provided with a guide port 8 adapted to the docking port 5, and the bottom side of the docking port 5 is flush with the bottom side of the guide port 8, or the bottom side of the guide port 8 is slightly higher than the bottom side of the docking port 5. When the docking port 5 is docked with the guide port 8, the powder can be introduced into the guide tube 3.

[0035] The inner liner tube 6 is provided with a guide plate 9 for closing and cutting it off. The guide plate 9 is tilted, and the bottom side of the guide plate 9 is aligned with the bottom side of the guide port 8. A smooth arc surface is provided between the edge of the top surface of the guide plate 9 and the side wall of the inner liner tube 6 to prevent the powder from being stuck in the seam of the edge. Through the guide surface, the powder falling into the inner liner tube 6 can only be pushed to the guide port 8 through the guide surface.

[0036] The bottom side of the inner liner pipe 6 penetrates downwardly through the bottom end of the butt joint pipe 2 , so the butt joint 5 that is not butt jointed with the guide opening 8 can be blocked by the side wall of the inner liner pipe 6 .

[0037] The bottom end of the lining pipe 6 is provided with a second flange 15 fixedly mounted thereto, and the bottom end of the butt pipe 2 is provided with a first flange 16 located above the second flange 15, and a bearing is installed between the first flange 16 and the second flange 15 to achieve a rotational installation connection between the two.

[0038] A coaxial gear ring 10 is fixed to the bottom end of the inner liner tube 6, and a driving gear 12 is meshed on the outer side of the gear ring 10. A mounting platform 11 is fixed on the side wall of the butt-jointed tube 2, and a rotating shaft 13 is rotatably mounted on the mounting platform 11. The bottom end of the rotating shaft 13 is key-connected and fixed to the driving gear 12. A stepper motor 14 is fixed on the mounting platform 11, and the output shaft of the motor is connected to the rotating shaft 13 to realize the control and drive of the rotation of the inner liner tube 6.

[0039] Based on the control of the stepper motor 14, the liner pipe 6 has at least three travel positions relative to the butt joint pipe 2:

[0040] First material discharge position: the guide port 8 is connected to a docking port 5;

[0041] Second material unloading position: the guide port 8 is connected to another docking port 5;

[0042] Parking position: the guide port 8 is not connected to the two docking ports 5, and the two docking ports 5 are blocked by the outer wall of the inner lining pipe 6;

[0043] The inner liner pipe 6 has a continuous unloading working mode, in which the inner liner pipe 6 has a single first rotation stroke of 180 degrees relative to the butt pipe 2, and two adjacent rotation strokes can be in the same direction or in the opposite direction, so as to realize the alternating continuous uninterrupted unloading of the two guide pipes 3.

[0044] Based on the above structure, the auxiliary device can be used for double-station continuous operation. Two workers can be on one side of the two guide tubes 3, respectively, and each can put on and take off the packaging bag without interfering with each other and without waiting for each other. When one worker is filling, the other worker can put on the packaging bag and prepare. When the previous worker finishes filling, he can directly fill the packaging bag of the other worker without interruption, thus realizing continuous packaging operation without stopping. There is no need to open and close the valve between adjacent packages, which saves time and reduces the loss of valves.
